Nils’ K1v
Key Features
- Recreates the Kawai K1’s 8-bit synthesis approach with additive and PCM waveforms.
- Four independently editable sources per voice support layered and changing digital timbres.
- Includes 1,352 editable Single and Multi presets drawn from factory, ROM-card, and PHm Pop Synth Module banks.
- Searchable banks and project-stored presets make the large sound library practical inside a DAW.
- DADSR envelopes, velocity curves, key tracking, and modulation controls open up deeper sound shaping.
- Paired-source amplitude modulation and the source-balance joystick add movement beyond static rompler playback.
- SysEx import, export, and parameter exchange support both hardware K1 workflows and external editors.
Description
Nils’ K1v is a software emulation of Kawai’s 1988 K1 rompler, built around the original instrument’s 8-bit waveforms, PCM material, and four-source voice structure. It brings the K1’s digital pads, bells, basses, and shifting layered timbres into a DAW while making the underlying sound parameters easier to reach than on the hardware.
The included library is unusually deep for this style of instrument: 968 Single presets and 384 Multi presets cover the factory bank, ROM cards, and the Kawai PHm Pop Synth Module. Banks can be searched, and both Single and Multi sounds remain editable and save with the project.
Each voice combines up to four sources with DADSR envelopes, velocity curves, tuning, key tracking, modulation, and amplitude modulation between paired sources. The source-balance joystick is especially useful for moving between layers during a performance rather than treating a preset as a static sound.
K1v can also exchange SysEx with a real K1, so it can import and export presets and banks as well as respond to supported hardware-style requests. That makes it a focused choice for producers after recognisably late-1980s digital character, K1 owners who want an editor, and anyone who wants to reshape the extensive supplied library.

Frequently Asked Questions
What kind of instrument is Nils’ K1v?
It is a rompler-style software emulation of the Kawai K1 digital synthesizer. Its engine combines 8-bit additive and PCM waveforms, with up to four sources per voice.
How many sounds are included?
The official page lists 968 Single presets and 384 Multi presets, for 1,352 sounds in total. These include the original factory bank, ROM cards, and Kawai PHm Pop Synth Module Singles.
Can K1v work with a hardware Kawai K1?
Yes. K1v can import and export SysEx presets and banks, and it can transmit and receive parameter changes via SysEx. The developer also documents support for selected SysEx requests and MIDI program changes with Bank Select.
Can I change the supplied presets?
Yes. Both Single and Multi presets are fully editable, and the page states that all 1,352 presets can be stored as part of a project. The source-balance joystick can also be used for real-time layer control.
